Three-Way Specification Comparison
Renault Duster in short
The Duster is back — the nameplate that created India's midsize SUV segment returned in 2026 on the Renault-Nissan CMF-B platform it shares with the Nissan Tekton, with butch third-generation styling, a 5-star Bharat NCAP rating and six standard airbags. There is no diesel or AWD this time, but the 160bhp 1.3L turbo-petrol is among the punchiest engines in the class and a 518-litre boot leads it, while a strong-hybrid version is expected around Diwali 2026. It takes on the Hyundai Creta, Kia Seltos, Maruti Grand Vitara and its own alliance twin, the Tekton.
